Plural of getting; instances of obtaining or acquiring things, or the things that are obtained or gotten.
From 'getting' (get + -ing) plus the plural suffix '-s', forming a noun meaning multiple instances or results of the act of obtaining.
This archaic plural form appears in older texts to mean 'gains' or 'acquisitions'—it's a reminder that many nouns English speakers now treat as uncountable ('getting') used to be countable.
